I am on the fence about this one, for a few reasons. DD has an idea of range but not necessarily anything else (she is 11). She is pretty bright, DYS, takes the top off of grade level standardized test and so far out of level tests. That being said there are so many other important things that determine success. Executive function, motivation, conscientiousness, and a whole host of other factors not in their control. It seems to me that sometimes having this info puts undue pressure on children. Parents think of it as some sort of indicator of future success (not all but some) and it really is not.
